The humble hamburger rarely has a place in traditional fine dining, but for many top chefs it's one of the food world's greatest guilty pleasures.
It's a simple dish that's found everywhere and loved all around the globe. But where can you get the best one and what's the secret to turning a handful of minced beef (or something else) and some bread into a delicacy? We asked the culinary elite - chefs laden with Michelin stars and other accolades - for their favorite burgers when they are having a sneaky time out from gastronomy.
Here are their picks.
Australia
Burger Project, Sydney
Neil Perry of Rockpool Bar & Grill is the big-name chef behind Burger Project, which works with local suppliers. The patty is hand-made, 100% grass-fed beef. Try the American, with Cape Grim beef, cheese, pickles, onions, mustard, secret sauce & rose mayo; or a simple cheeseburger.
Chosen by Scott Collins of MEATliquor, London
Butchers Diner, Melbourne
This 24-hour, hole-in-the wall joint with a counter and stools is a favorite with chefs who enjoy its unfussy food with high-quality ingredients. The hamburger is a 120-gram beef patty with tomato sauce, pickles & mayo in a milk bun.
Chosen by Ashley Palmer-Watts, formerly of Dinner by Heston Blumenthal, London
Butter, Sydney
Butter is a hybrid sneaker, fried chicken and Champagne bar in Surry Hills. If that sounds an unlikely setup, it is the project of respected chef Julian Cincotta and the team from Thievery restaurant in Sydney. The OG Chicken Sandwich is not to be missed.
Chosen by Josh Niland of Saint Peter, Sydney
Mary's, Melbourne
This is an outpost of a Sydney chain, with loud music, natural wines and an American vibe. Founders Jake Smyth and Kenny Graham favor local suppliers for their meat and wines, and big flavors. The cheeseburger is a must unless you'd prefer the vegan menu.
Chosen by Andrew McConnell of Cutler & Co., Melbourne
China
Honbo, Hong Kong
This homage to the classic American burger joint serves great food. The patties are made with Double Gold American beef from Wisconsin, served in a potato milk bun. The double cheeseburger is the signature option.
Chosen by Shane Osborn of Arcane, Hong Kong
Denmark
Gasoline Grill, Copenhagen
Fresh organic burgers are cooked at this walk-in joint, which is attracting attention far beyond Denmark. Housed in a former gasoline station, it has a short menu like a simple roadside grill. It's worth going off piste with the vegetarian Green Burger.

France
Badia, Grand Hotel Thalasso, Saint-Jean-de-Luz
This grand old hotel overlooking the bay of Saint-Jean-de-Luz is an idyllic spot to eat. And Le Burger is particularly good, featuring truffled bread, Charolais ground beef, Basque sheep's cheese and Espelette pepper ketchup with fries.
Chosen by Shane Osborn of Arcane, Hong Kong
Bioburger, Paris
As the name suggests, this Parisian restaurant serves organic burgers and they are full of flavor. One favorite is Le Poivre: a choice of beef or vegetable patty with farmhouse cheddar, tomato, salad, onion jam and pepper sauce. It's like eating steak au poivre on a bun.
Chosen by Greg Marchand of Frenchie, Paris
CAB Comptoir a Burger, Biarritz
This restaurant is located close to Les Halles, the daily market in Biarritz, from which the chefs source the freshest of produce. The buns are cooked to a special recipe and all the sauces are homemade, says Paris-based chef Helene Darroze. Try Le Parm, with a Parmesan tuile, Mozzarella and arugula and pesto with sun-dried tomatoes.

Wagyumafia, Tokyo
The Cutlet Sandwich from Wagyumafia at Nakameguro station is made with thick-sliced pure Kobe beef, breaded and deep fried, sandwiched between two slices of Japanese milk bread with a secret house-made sauce. It harkens back to the original burger at Louis' Lunch in New Haven, yet is distinctly Japanese, says three-Michelin star chef Kyle Connaughton. The prices are something else. The budget (Zabuton) version is 5,000 yen ($45.50) rising to 50,000 yen for the Kobe Champion.
